Abstract
Zajedno s proširenjem podruˇcja primjene, rastu i potrebe za efikasnim naˇcinima kodiranja i dekodiranja kljuˇcnog dijela multimedijalnih sadržaja – video signala. U ovom je radu opisana izvedba vrlo brzog dekodera MPEG–4 Simple profila. Uz sve alate za pove´canje efikasnosti kodiranja i otpornosti na pogreške koje podržava Simple profil, podržan je i Dynamic Resolution Conversion alat iz Advanced Real Time Simple profila. Pri kodiranju s niskim brojem bita u sekundi, njegovom se upotrebom ostvaruje pove´cana efikasnost kodiranja bez smanjenja kvalitete slike, u odnosu na Simple profil. Ta se razlika može iskoristiti za poboljšanje kvalitete slike ili za smanjenje broja bita potrebnih za kodiranje. Za prikrivanje kvantizacijskih efekata, izvedena su oba MPEG–4 filtra za postprocesiranje, a izložen je i novi postupak adaptivnog odred¯ivanja razine primjene tih filtara, koji omogu´cava da se za svaki dekodirani VOP odabere minimalna razina primjene koja je dovoljna za ostvarivanje maksimalne kvalitete obrad¯ene slike. Opisana usporedba sa sliˇcnim radovima jasno pokazuje prednost ovog dekodera po pitanjima brzine i kvalitete rekonstruiranog video signala.
Abstract (english)
As the application area of multimedia widens, needs for effective way of coding and decoding it’s essential part – video signal, is also growing bigger. This thesis presents very fast implementation of MPEG–4 Simple Profile decoder. Along with all the coding efficiency and error resilience tools supported by Simple Profile, the Advanced Real Time Simple’s Dynamic Resolution Conversion tool is also supported. In low-bit-rate video coding, it’s usage helps raise coding efficiency with no loss of video quality, when compared to Simple Profile. This difference may be exploited to achieve considerable improvements in image quality or to further lower bit rate. To conceal quantization artifacts, both of the MPEG–4 postprocessing filters have been implemented. Also, a new procedure for adaptive selection of postprocessing filter appliance level has been proposed. This procedure makes it possible to adaptively select minimal level of appliance, which would result in highest quality of processed image, for each decoded VOP separately. Presented comparison between this and similar works clearly shows the advantage of this decoder at the points of speed and quality of reconstructed video signal.
